/**
 * \brief Class to read/write a DataElement as ExplicitImplicit Data Element
 * \details This class gather two known bugs:
 * 1. MDCM 1.2.0 would rewrite VR=UN Value Length on 2 bytes instead of 4 bytes
 * 2. MDCM 1.2.0 would also rewrite DataElement as Implicit when the VR would not be known
 *    this would only happen in some very rare cases.
 * mdcm 2.X design could handle bug #1 or #2 exclusively, this class can now handle
 * file which have both issues.
 * See: mdcmData/TheralysMDCM120Bug.dcm
